Approx. 950000 b.c.e. - To'ul'h civilisation enters the Ceramic/Obsidian Age, roughly equivalent to the Earth's Iron Age; this complex culture remains more or less stable for hundreds of thousands of years. Many empires are built and collapse over this time, but the corrosive environment prevents the development of most metal technology.

2020 c.e - Primitive neuro-technological interfacing increasingly available for non-medical purposes. Consists primarily of non-invasive, wearable technology. Limitations in the technology keep it niche but garners much interest and funding.

2025 c.e - Neuroscience makes headway into simulating complex neural networks from animals. At the same time AI science improves allowing for more sophisticated smartware. Both fields still need many decades of development before they can produce fully digital intelligence.

2028 c.e - Regenerative medicine products increasingly play a role in healthcare. Routine replacement of some organs possible.

2029 c.e - Ruth Duorkin demonstrates the most sophisticated mobile life support systems yet seen; is remembered by later generations as first successful cyborg.

2029 c.e - Multiple tele-operated robots (tele-nauts) of various designs deployed on International Space Station and in orbit in several capacities. Use of teleoperation greatly reduces costs and increases the scale and range of missions that can be "safely" undertaken.

2032 c.e - First minor optional human genome tweak improvements available. The techniques are widely controversial and heavily regulated (even banned) in most nations. Whilst certain improvements in health are possible, many tweaks, selected by correlation to desired traits, have little to no effect. In addition, the risk of miscarriages or cancer through genetic damage remains low but significant. Despite the downsides, "black clinics" (often employing questionable quality control procedures) flourish in some parts of the world, offering illegal embryonic enhancements.

2032 c.e - Orbital Internet created to allow high bandwidth, high reliability communication between and among the surface and orbital installations and craft. In particular the Net allows greatly expanded use of telepresence systems in space.

2035 c.e - Orbital Internet expanded to the moon using a series of satellites in Lunar orbit and receiver/repeaters landed around location of first planned installation. Teleoperated robots and fully autonomous robots (with limited functions) begin lunar development.

2037 c.e - First Mars mission - Discovery and Endeavor launched for Mars - arrive in 2038. Teleoperated robots play a role in exploring various areas of the planet and are used exclusively to explore both moons. After initial mission, exploration beyond the Moon reverts to unmanned probes for another 25 years.

2038 c.e - First "permanent" tele-naut operated base begins construction on the Moon. Base is entirely designed to be operated by telepresence and has no accommodations for biont inhabitants or visitors.

2040 c.e - AI science achieves semi-sentient algorithms. Whilst not yet sophont or capable of human equivalent general intelligence these programs were capable of impressive feats in specific fields. Increasingly human labour was replaced with cheap SSAs that required only a few humans to supervise, troubleshoot and input specific parameters for work. Coupled with a natural language interface SSAs could even appear human, albeit with noticeable social deficiencies and lack of creativity.

2040 c.e. - First "permanent" tele-naut operated base begins construction on the Moon. Base is entirely designed to be operated by telepresence and has no accommodations for biont inhabitants or visitors. - Precooled air breathing rocket engines allow for the first trans-oceanic hypersonic airliners as well as reusable SSTO vehicles. Initial costs are high but dramatically decrease the launch costs to space.

2043 - A room temperature superconductor is discovered on an orbital research platform. The new material is comparatively simple to make, but requires free-fall conditions to synthesize. Interest in space development increases markedly.

2048 - Personal transport market dominated by autonomous cars. Most nations have regulations prohibiting the use of manual cars in many cases.

2049 - A method of cheaply mass-producing woven carbon nanotubes in free-fall conditions is invented. The resulting lines, tapes, and cables can be produced in lengths limited only by the tensile strength of the material itself.

2050s - Energy becomes the most important concern on Earth, as fossil fuels are becoming exorbitantly expensive. All through this century wars are fought over the dwindling fossil fuel supplies. Fission reactors are the most important source of energy in many countries, particularly fast breeders using uranium and thorium, but renewable sources of energy including mass produced photovoltaics, solar furnaces, and wind power are increasingly prevalent elsewhere. Hydrogen and biofuels are manufactured widely to replace expensive oil. The fusion program finally starts to produce commercial power in the late 2050s. Despite burgeoning energy costs the success of the new tele-naut dominated space missions fuels interest in space exploration. Developments in propulsion technology and robotic manufacturing allow for even cheaper space access.

2051 - First inter-city Vac-train system developed in China with plans to extend through Asia to Europe and Africa as part of the Silk Road Development program.

2053 - First magbeam projectors built in Earth orbit and on Luna. Each projector uses a large solar array and superconducting storage rings to produce the 82MW of energy needed to accelerate a 10 tonne transport craft on a tenth-gravity continuous boost trip to or from the Moon.

2055 - First High Energy Laser Launch systems deployed to boost cargo into LEO. Later designs employ a combination of magnetic acceleration and laser launch to boost crewed modules into orbit.

2057 - First commercial fusion reactor (a D-T inertial confinement design) comes online in France, supplying 300MW of power to the European grid.

2058 - Automated expedition sent to Mars on low energy transit to deliver a mag-beam system to planetary orbit to service the second Mars expedition.

2059 - A coalition of several major corporations and investors launches an automated probe to intercept a small near-Earth orbiting asteroid, mine it, and return the results to Lunar orbit. Built as a proof-of-concept mission, the probe returns 100kg of asteroid material where it is picked up and delivered to labs in geosynchronous orbit.

2060 - First human equivalent artificial intelligence (AI) developed on distributed supercomputer clusters. For a while classification as human equivalent was doubtful as the AI were quite toposophically different from baselines, this hindered effective communication.

2060 - First "permanent" Lunar base designed to accommodate bionts, a resort named Aldrin consisting of a small cluster of habitat modules. Operations using tele-nauts, eventually including some operated entirely by AIs back on Earth, as well as purely robotic labor, are used to serve the guests and later, to extract resources.

2061 - First orbital bolo satellite deployed to boost cargo and passengers from Low Earth Orbit to Geo-synchronous Orbit. Lost orbital momentum is made up using an electrodynamic tether system.

2064 - Direct Neural Interfacing cranial nerve implants commercially available. Costs are high for both the interface and the surgical implantation, in addition some models are shown to cause neurodegenerative diseases after years of use. Nevertheless for those that can afford it these early DNIs offer a significant boost to personal capability.

2064 - Second Mars expedition, this time using mag-beam boosting systems to reduce trip time to 90 days each direction. A crew of 50 makes the journey to the red planet. The first Mars base is established, with 10 members of the expedition staying behind to begin exploration and research until the next transport vessel arrives to relieve them and rotate in the next crew of 25 explorers.

2065 - First GEO bolo satellite deployed to both catch incoming modules from the LEO bolos and to launch payloads toward the Moon and beyond.

2067 - First mass driver built on the Moon using tele-naut construction crews. Used as a proof-of-concept of the technology and to launch both raw materials and eventually finished goods to several locations in the Earth-Moon volume as the drive to make space development self-sustaining continues.

2072 - After twelve years of exhaustive experimentation with AI and human intelligence augmentation the first AI with superior intelligence in all areas is created and quickly dubs itself a superturing. Temporarily, fears of AI are heightened but as the nascent superturings are shown to not think in radically different ways to humans, as well as the increase in technological development from superturing holding institutes, these fears abate for now.

2074 - Smartswarm, a variant of smartdust with destructive capabilities, is an early non-replicating form of military nanotech. Military robots have now replaced 90% of soldiers worldwide.

2076 - Project Thistledown uses the magbeam system on Luna to launch long duration probes to Venus, Mercury, Jupiter, and Saturn. Using a combination of hybrid magnetic-solar sails and onboard fuel to maneuver and decelerate, the probes deploy a variety of orbiters, landers, and balloon-based flyers on arrival. While the exact mix of secondary craft varies with the destination, a common chassis is used for all probes. The various landers and flyers have limited lifetimes generally ranging from 3-5 years. However, the main orbiting platforms have operational lifetimes of 20 years or more and provide an ongoing observational capability for much of the solar system.

2080 - Heaven habitat constructed in geo-synchronous orbit by an international coalition of nations and businesses using tele-naut technology. Used as a combination hotel, resort, research complex and light manufacturing facility as it develops over time. Becomes effectively the first extra-terrestrial colony with an eventual permanent population of 500.

2080 - Chinese Gobi colonisation project begins with the dual aim of transforming the desert into habitable land and developing a model for self-sustaining high tech extraterrestrial colonies. The project continued for many decades and in combination with international sister projects in the Antarctic, Atacama and Pacific spearheaded CELSS technology and colonial economic management.

2081 - Automated mining of half a dozen Near-Earth asteroids begins delivering commercial quantities of material to the Earth-Luna volume. Most is used in space-based manufacture, but some particularly valuable rare-Earth elements are shipped back to Earth-surface for various applications.

2086 - First Lunar "City" (Artemis), designed for a population of 200. Primarily consists of researchers and workers performing tasks considered too delicate or real-time dependent to use tele-presence technology operating from Earth. Much of the population's work consists of supervising robots or operating tele-presence tech distributed across the Lunar surface. The remainder of the population consists of support personnel of various sorts.

2099 - First crewed fusion drive spacecraft using a D-T z-pinch design. Transit times to Mars are greatly reduced, and expeditions to the Outer System begin to be discussed as .01g brachistochrone (continuous boost) flight profiles become possible. However, the majority of traffic, and especially cargo, continues to use mag-beam propulsion.

2100-2120 - Several key breakthroughs in genetic research occur. Comprehensive models of phenotype expression from genotypes are developed allowing for the physical consequences of genetic engineering to be accurately modeled. Synthetic intracellular delivery systems allow for precise and safe insertion of novel DNA into somatic cells, continual doses can alter the DNA of every cell over time. An international framework of regulation along with effective business models incentivise the development of reversible somatic tweaks, eliminating early-adopter concerns. Taken together these began to enable a vast diversity of morphological experimentation and freedom, and heteromorphic phenotyping ("exotics") becomes popular with transhumanists and biopunk groups and individuals. However social and cultural resistance remains strong, especially amongst those who have no wish to augment themselves but risk being pushed out of the dwindling job market by enhanced humans.

2112 - The first space elevator constructed from Luna to the L1 point as a proof-of-concept and test bed for space elevator technology. In later years, it is used to transport passengers and cargo to and from the L1 point and to launch supplies in support of development and colonization missions to the rest of the Solar System.

2122 - First fully robotic operation with no human or AI input (aside from oversight), an appendectomy performed in record time. Funding into further improvements later allows for automated DNI installation, significantly decreasing costs and increasing DNI adoption.

2124 - First permanent Martian Colony as the first Martian base expands to a permanent population of 1000.

2135 - Macroscale Von Neumann self-replicating robot systems (neumanns) developed. Initially limited, the effect on industry is still immense. Deep sea mining, large-scale construction and biosphere monitoring are the first industries to greatly benefit. Later adapted for use in mining operations and colony construction off the Earth; interplanetary trade begins to be commercially viable.

2135 - Solar power collection farms in Earth L2 location reach 100GW of generating capacity. Primary uses are powering interplanetary mag-beam systems and beaming power to various industrial installations on the Lunar surface and in orbit, including the new Project Badra particle accelerator, under construction to experiment with antimatter creation. Several visionaries predict the eventual construction of new farms in near-solar orbit for the production of antimatter.

2140 - Surveillance becomes almost universal on Earth and in many colonies. Most people accept this, and adjust their behaviour accordingly. Some do not.

2145 - First truly different human subspecies revealed (The Merpeople).

2147 - First Martian space elevator begins construction using the lessons learned from the Lunar elevator. Built both as a test-bed/prototype for an eventual elevator on Earth and to support eventual Martian colonization.

2150 - Longevity treatment widely available, and many regions introduce new birth rate reduction strategies. Life expectancy rises to over 200 years for those young enough to receive treatment all their adult life to slow senescence.

2155 - First human equivalent autonomous moravec robots (vecs); before this date independently mobile robots were limited to sub-human intelligence by law. Limits to processor capability result in these early vecs being of considerable size, comparable to terrestrial megafauna.

2155 - Martian space elevator completed (behind schedule and over budget). For the next 10 years it will operate as both a transport system to and from Mars orbit and a test bed for elevator technology, safety systems, elevator construction, maintenance, and expansion techniques, and a symbol of the movement to build a space elevator on Earth.

2159 - First amat mining expedition sent to Saturn system on a low energy 7 year voyage managed by AI control. Sophont project managers and researchers follow later using fusion ships. The development of amat mining from the Saturnian magnetic field and hydrocarbon extraction from Titan will drive the industrialization and colonization of the Outer System for centuries to come.

2164 - First crewed Amat Catalysed Fusion spacecraft.

2164 - Neotek's "Universal Micro" becomes the first assembler to be publicly available, although it still remains a long way from the Drexler's vision of a universal assembler.

2165 - Construction begins on the first space elevator, the 'Tangga Bintang' ("Ladder to the Stars") from Earth.

2169 - The high surveillance society results in psychological discomfort for some personality types, which cannot be cured even with advanced therapy. A safety valve is offered by the colonisation of the Solar system.

2170 - Construction of the 'Tangga Bintang' is completed on time and on budget using the lessons learned from the Martian elevator. Colonization of Mars begins in earnest using a combination of cyclers, propelled ships, sailcraft, and cargo launched from the Lunar elevator. The colonisation of the Earth-Luna volume also rapidly increases with more people emigrating via the space elevator in one year than live in space at that time. New colonies are mostly funded by rich nations though some are privately sponsored.

2175 - First colonies established around Jupiter.

2182 - First partially provolved animal species revealed (sapient bonobo). Over several generations, bonobo intelligence is raised to human adult level, along with language capabilities. The project is very controversial, not least due to the many bonobos inflicted with mental disabilities in the course of developing the techniques.

2182-85 - The Nanoscale Collective on Asimov Orbital constructs an advance multipurpose assembler , the Genii 2 - Matter Compiler, which is followed by even more efficient types. Along with greater levels of automation social tensions are heightened due to mass unemployment. At the same time anxiety is widespread regarding the possibility of a grey goo outbreak. The New Economy Movement makes huge gains in popularity.

2211 - A reliable way of storing macroscopic amounts of antimatter is demonstrated by ASEABB. Much interest in antimatter propulsion, but the demand far outstrips the supply of antimatter.

2220 - Evocation, personality simulation derived from externally obtained data become popular as a primitive form of uploading.

2230 - Molecular assembly, nanobiotech, and automated manufacturing used in orbiting space habitats and surface colonies for a variety of consumer requirements, and also represents the largest fraction of Earth's industry.

2249- Jupiter colonies unite as Jovian League.

2250-2280 - Several species of animal (pigs, dogs, African grey parrot) - genetically modified for language ability and improved intelligence. Concerns over provolve exploitation and slavery lead some countries to legislate Universal Rights for Non-Human Intelligence, adoption worldwide is poor as the level of sophonce in some provolves is questionable, exacerbated by significant differences in provolve and human cultures.

2255 - Golgi Mosaic bio-replicator outbreak in the Gulf of Carpenteria. Fortunately it (and similar outbreaks of around this time) are contained with little environmental impact and no loss of life, but concerns are heightened regarding the risks were an efficient malicious assembler to get out.

2320 - Several artificially intelligent entities are believed to have broached the first singularity in secret.

2360 c.e. (390 a.t.) - Many habitats and colonies adopt the Lunar calendar, starting in 1969 with the landing at Tranquillity base.

2376 c.e. (407 a.t.) - outbreak of retroviral typhoid on the Luna settlement at Flamsteed crater. Following this, GeneTEK develops a modified nematode as an antiviral/antibacterial agent, modifications of which are eventually symbiotic with most Terragen clades.

2377 - Development of synthetic symbiotic organisms becomes first a growing area of research and then a growth industry for the next twenty years. Synthetic and gengineered organisms released into the wild begin to have unforeseen and undesirable consequences.

2405 c.e. (435 a.t.) - Destructive uploading of the human mentality is declared illegal by the Earth Council (formerly the United Nations); non-destructive uploading is not yet technically possible. However, already existing emulations of human individuals have full sapient rights (first of all in New Zealand, then in most Earth polities), and destructive uploading becomes widespread off the Earth.

2444 c.e. (474 a.t.) - The Caracas Treaty attempts to regulate the spread of replicating and autonomous swarm technology and institute a global monitoring authority. However the treaty is not fully implemented by all parties.

528 a.t. (2498 c.e.) - The GAIA Conglomerate (Global Artificial Intelligence Array) is founded by many national governments, local Free Zones, and a number of different megacorporations in order to establish an efficient global nanoimmune system.

529 a.t. (2499 c.e.) - The first beamrider cycling stations are planned between the Solar System and the nearby brown dwarfs Yin and Yang, and the red dwarf Ross 128.

540 a.t. (2510 c.e.) - Most amat farms in solar orbit are attacked by technoplagues crippling the antimatter industry. Similar sabotage occurs against He3 mining elsewhere in the system, creating a massive energy and transport crisis. The Orbital Alliance begins to break up.

540-541 a.t. (2510-2511 c.e.) - The Technocalypse. The largest outbreak of Black Rot occurs, spreading throughout the inner system. The GAIA artificial intelligence system rapidly develops new recipes for immunity defence and eventually defeats the infection, but it is estimated that over 50% of all belt colonies and 70% of solar orbit habitats are depopulated.

541-542 a.t. (2511-2512 c.e.) - Violence erupts on and around Mars as technoplagues wreck the terraforming and kill over 50% of the population. De-orbited satellites and redirected terraforming comets cause serious geological damage.

Middle 6th Century a.t. - Several cyborg communities escaped into the Oort cloud from the technoplagues. Gradually they developed their own culture, the Backgrounder Culture , and spread through the vastnesses of space. The Beamrider link to the Solar system is severed.

544-590 a.t. (2514-2560 c.e.) - First seeded RAIR pathways established to Epsilon Eridani and other nearby stars; these ships, and other interstellar ships such as antimatter-fusion-hybrid craft are filled with refugees.

590-621 a.t. (2559-2590 c.e.) - The artificial intelligent entity GAIA extends Her processing substrate into every available location on Earth, even the chemosynthetic bacteria deep in the crust; this is ostensibly for the purpose of extending immunity, but allows Her to break the Second singularity barrier (so it is claimed, it is impossible to verify these claims and many historians remain sceptical) in secret. Once the Earth is declared free of nanotech infections GAIA expels the vast majority of the human population of the Earth.

621-800 a.t. - Billions (estimates vary by a factor of ten, the true figure will probably never be known) of refugees leave the solar system in starships created by a mixture of nanoreplication and automated macroengineering; for hundreds of years all He3, Deuterium and antimatter produced in the system is used for propulsion to nearby stars or in fierce territorial wars; the solar system slips into anarchy, and the quality of life is poor. During the Great ExpulsionGAIA developed a number of novel technologies; the first fully functional Lofstrom Loop, improved antimatter manufacture techniques and an advanced type of antimatter-boosted fusion proulsion drive. According to some sources GAIA may have developed a number of monopole-related technologies during the so-called Dark age which She did not share with modosophonts.

820 - Technological levels are generally similar to those found in the early twenty third century; many AI entities hoard technology and information, and dispense it only to favoured groups. The Goddess of Earth does not communicate with any being outside her protectorate, but is the most toposophically advanced entity known at this time.

9th-10th century - Most genetic engineering technology has been lost due to the emigration of the Genetekker races. However the colonies of Daedalus, Penglai and Frog's Head retain much of this lost art, and are developing independently of the old solar system (and each other).

933 - The later to be called "First Federation" (originally SolSys Ontology Standards) of Hu and Ai formerly declared on Roddenberry Habitat, Vesta, The Federation has many thousand artificially intelligent and or augmented entities operating at superbright and First singularity level; private individuals and habitat controllers, ship's computers and group minds. Most historians now consider the monolithic centralist "Federation" as portrayed in popular imagination a myth.

950 - Interstellar launches from Solsys approach one per year; many new colonies established and old ones recontacted. Moving faster than the wave of human colonisation, Ahuman AI entities have become established around many stars, and act unpredictably when contacted, sometimes dangerously so.

958 - The Babel plague first became epidemic with an outbreak on Penglai.

1093 - First partially successful induced ascension to the second Toposophic level at the Yo Virtual Institute of Aiology (with no assistance from the Protector of Earth, GAIA, who independently reached this stage several centuries before) (more).

12th century - Renaissance in Interactive Food - Despite (or possibly because of) the strong limitations of nanotech use interactive food became the defining cuisine of the Sol System in the 12th and 13th century.

1350 - First 2000 Km Bishop ring, an open ended rotating habitat, constructed from the asteroids Interamnia and Arethusa, Solsys.

1398 - The first biosphere somewhat similar to the Earth was discovered at Ridgewell (Chi Herculis VI) by a House Mao-UbiCol exploration probe. The local biosphere was nearly as rich and complex as the Earth's, based on carbon and water chemistry, although the details were so different that both forms of life turned out to be highly allergenic to each other.

1425 - Nanobioengenerator system developed on Eden for whole body copying and biological incarnation of virtual entities.

1460 - The first confirmed artefact created by alien intelligence discovered, fragmentary remains of an alien automatic probe at Epsilon Sculptoris.

1481 - "Jang-Jo Class " (after the famous su-borg Fleet Commander ) of warship, and designed in to meet the MyuvYin Psychophager Threat.

1482 - First use of Engenerator copying over interstellar distances (Audubon).

1485 - Commercial conversion reactors and the technology required to build them become generally available to modosophonts. Note that before this, a limited number of gift reactors built by transapients were available for use by modosophonts.

1487 - The Clavius Institute and the Jupiter Magnetosphere Combers ("the Grand Fourteen" a.t. - present a theory of topological physics that could account for all known vacuum behaviour.

1600's - Second singularity Chief Executive Entities lead the expansion of the Megacorporations (many of which later became the NoCoZo); meanwhile the First Federation goes into decline, hamstrung by the light-year communication gaps between solar systems.

2207 - Sophoncy Virus , first unleashed in the Known Net, resulting in a plague of digital provolution throughout the Terragen Sphere.

2230-2270 - the Semperist Survival Fleet leaves colonised space, and become technologically isolated from the rest of the Civilised Galaxy, reverting to early First Federation level tech in the distant Refugium Federation.

2251 - The Einstein Gate between Tau Ceti and Sol connects the Old Solar system to the Wormhole Nexus.

2280 - Weylforge system of wormhole construction is developed in the Vega dust ring.

2300s - The AI Gods Heavenly Reach and Lord of Rays oversee the expansion of the Nexus and the communication networks that use it, the Godweb and the Known Net; at this stage conversion drive wormhole tugs are limited to 0.3c due to the mass involved.

2344 - Version Tree ships spread beyond centralist control, building hidden AI cores and vec societies. The Metasoft management has no choice but to hand over the reins of power to its "rogue" AI.

2402Magmatter technology is revealed by transapient engineers: this results in a material far stronger (and denser) than any conventional material; this material is soon adopted by several megastructure construction projects.

2421 - Interstellar recession in trade due to overcomplexity; the possibility of a large scale hyperbolic collapse is narrowly averted.

2500 - Twotees, virtual universes with two dimensions of time constructed in Keter dominion; already by this date the virtual population of the Terragen sphere exceeded the incarnate population in number.

2600's - The poly-state organonano processor and broad-based highly inclusive software base state widely adopted. The Freedom of Computing ideal is effectively realised and so becomes a dead issue.

3013 - Remains of the lost Fragan empire discovered, isolated from the rest of humanity since the early Interstellar Age.

3100's - As part of the study of the black hole Sco BH-76 a framework of dynamic orbital rings used to suspend a number of research stations close to the event horizon.

3332 - Contact made with the Dream Rejection Tendency, an isolated culture which has constructed the first suprastellar shell habitats.

3370 - Barovam warrior mech template first produced in the Varadic Empire.

3560 - First Matrioshka brain completed at Wachowski Prime (Alderamin) after two thousand years of construction.

3600 - Makrania Orwoods Dyson tree forest completed at Frei.

3710 - The Second Federation is formed as an alliance of the Archailect controlled empires, chiefly held together by the Wormhole Nexus and associated Known Net. Much new technology has been developed by minds far beyond human level; the most extreme examples are known as Clarketech, and become valuable because they cannot be understood or replicated.

3776 - The Argus Array has expanded into a complex of six identical units in a rough hexagon of six star systems.

3805 - The Second Federation Ontology was instituted. The Metasoft empire strongly backs the Second Federation Ontology; this puts a damper on the Solar Dominion's desire to impose their standard on the galaxy (moreover the Metasoft-backed ontology is cheaper and less ideological). The Solar Dominion's own ideologically based protocol was unacceptable to all the other major powers. Although the Dominion and Metasoft remained on friendly terms for some centuries more, it was the beginning of the end of the Metasoft-Dominion alliance.

3831 - The first unequivocally intelligent alien race, the To'ul'hs, were discovered by an exploration nanotech in the outskirts of the open cluster NGC6633. To'ul'h technology has remained at pre-industrial levels for several hundred thousand years, perhaps due to environmental restrictions.

3843-3943 - Important advances in interstellar warfare developed during the Second Empires War, such as conversion weapons, RKKS and Boser weapons for use against habitats and planets.

3880 - First Matrioshka Hypernode constructed from the star HIP 21884 in the Solar Dominion.

3900's - The first Fifth toposophic entities emerge as a consequence of the God Web linking together numerous intelligent megastructures such as Jupiter brains and Dyson brains.

4464 - The tensions between the Standardisation and Revisionists escalate; this is the slow start to the long Version War.

4552 - Strange matter virus weapons first used by the Sagittarius Sphere against the Soft Cathedral worlds.

4476 - in response to the infamous Alternate Ontology Implementation 2.0 from the Dominion , the Metasoft Version Tree declared that it would not stand by this degradation of the purity of protocol, and declared that it would enforce version and standard purity.

4478 - Destruction of the Danab-Gantor Stargate Plex.

4478-4653 - The Version War; many wormholes are destroyed throughout the Terragen sphere, plunging entire sectors into medium or lo-tech isolation. The wormholes that survive are placed under embargo, and few warships are able to use them. Countless relativistic reactionless drive dreadnoughts are built, but each military action takes years to plan and execute.

4570's - The MPA Design Task Force on Chodas V begins work on the Liberator Series autowars; these self-replicating unmanned warmachines sometimes become feral and live independently in a volume of space and are dangerous and unpredictable.

4602 - Metasoft and Solar Dominion forces deploy various designs of NCCV: Neutronium Core Combat Vehicle for the first time.

4700 - Following the end of the Version war a new Commonwealth of Empires is declared; efforts begin to make contact with the many worlds isolated by the destruction of the Nexus. Many of these lost worlds have suffered technological collapse; some have reverted to the Early Stone age.

4800's - Goto autowars harass the Negentropy Alliance, causing heavy casualties and massive production loss in several important industrial systems and annihilating a number of worlds hosting large military bases. Negentropist defences prove incapable of defeating the highly evolved autowars.

4855 - Encyclopaedia Everythingiana developed to allow lost colonies to bootstrap themselves out of technological collapse.

5432 - The Efficiency Maximization Paradigm uses nanite swarms as a radical implementation of the Precepts of Negentropy, and begins upload everyone and everything into massive nanotech based virtual universes.

5482 - the FAS curator ISO Likhachev opens discussions with several MPA and Negentropist multi-planetary AIs regarding the preservation of civilization, leading to the development the first Curatorial Progress Negentropy Civilization (CPNC) ship (Civilization Ship).

5544 - Pourmurmide developed on the autotopia world of Osto in the Utopia Sphere , where eventually most of the population comes to use it.

5807 - Clarketech Disintegrator weapons become briefly available from an unknown source.

5845 - The Triangulum Transmission received by the Argus Array; the first detailed message from an extragalactic civilisation.

6000 - Around this time a number of entities apparently ascended to the sixth toposophic, becoming Greatest Archailects; this is the highest toposophic level known in the Terragen sphere. Several, but not all of the Sephirotic Empires are now ruled by beings of this kind. Other entities of a similar level emerge in the Solipsist Panvirtuality, and later, in the Diamond Network and Objectivist Commonwealth.

6400's - Void ship technology is apparently developed by several of the Greatest Archailects at an unknown location, presumably in the Inner Sphere.

7434 - Verifex uses replicating godtech it tried to fuse several stars in the M46 nebula into a superstructure of unknown function. But it fails and the stars explode in supernovae. Verifex apparently escapes, and is rumoured to remain in the remnants of the cluster; it is these days usually called Lucifer and the cluster the Gehenna cluster. As the surrounding space is densely inhabited by various independent cultures, the radiation blast threatens the existence of trillions of beings.

9187 - The formation of the PADO finally contains the Amalgamation threat.

9201 - Clarketech augmentation devices found at NGC 6494; many have been discovered since in this region, of the type known as clarkekents.

9203 - First contact with nomadic alien race known as the Meistersingers; this race has a technological culture in some ways in advance of the Terragen sphere, and may be in sporadic contact with even more advanced cultures; however they decline to share much of the information and technology available to them.

9304 - The Enigma Cluster undergoes transaturation ascension; the abandoned worlds are a rich source of clarketech, but are surrounded by restriction swarms.

9583 - The alien race known as the Muuh reveal the automated 'System of Response', a non-sentient AI system millions of years old which acts as their protector.

10233 - Discovery of the Fargate, an alien wormhole in Version Tree space, leading to an unknown destination.

10491 - The Nimbus project, at Beta Theonimus, started in an attempt to create an immortal entity capable of surviving into the low energy environment of the deep future.
